FABRIC-DYEING MACHINE.

Application filed. August 14, 1925. Serial No. 50,175,

This invention relates to improvements in dyeing machines, and hasparticular reference to a machine for dyeing textile fabrics.

An object of the invention is to provide an improved machine wherein apluralit of tubs containing various liquids utilize in the dyeingprocess are assembled and into which pieces of fabric are successivelyconveyed so as to subject said fabric to the action of the baths orsolutions in said tubs.

Another object is to control the .feeding of a fabric to the variousbaths in such manner that the fabric, after immersion in one of thebaths for a period of time, is, at the termination ofsuch period,automatically transferred to and immersed in a succeeding bath.

A further object is to provide an apparatus which will lift a fabricsupporting drum from one tub and deposit the same upon a platform formovement to a succeeding apparatus which is thereupon operable to lowerthe drum into another tub.

The above and other objects will appear more clearly from the followingdetailed description, when taken in connection with the accompanyingdrawings, which illustrate a preferredembodiment of the inventive idea.

In the drawings Figure 1 is a fragmentary side elevation of the machineconstructed in accordance with the invention;

Figure 2 is a fragmentary top plan View thereof Figure 3 is a sectionsubstantially on the line 3-3 of Figure 1; and

Figure 4 is an enlar ed fragmentary elevation of the drum lifting andconveying mechanism.

In'the dyeing of textile fabrics it iscustomar to subject the fabric toa plurality of bat s consisting of various solutions utilized toaccomplish the different steps in the dyeing process. It is alsocustomary to submit the fabric, depending upon its nature, to thevarious solutions or baths for predetermined intervals of time. Thus, asa specific example, which, of course, need not be strictly adhered to incarrying out the present invention, a fabric may be submitted to thefollowing bathsin succession for the stated periods of time, namel acid,five minutes; water, five minutes; b caching, fifteen minutes; water,five minutes; soap solution, fifteen minutes; water, five minutes;bleaching, fifteen minutes; water, five minutes; acid,

five minutes; water, five minutes; dyeing,

five minutes. In cases where the fabric 1s submitted to the action ofsolutions for periods of more than five minutes, such as the bleachingand soap solutions, a number of tubs containing the same solution areplaced in succession. Thus, where the bleaching is carried on forfifteen minutes three tubs containing the bleaching solution arearranged one following the other, it bemg understood that the fabric istransferred from one tub to the other at the termination of apredetermined period of time whlch, in .the present example, is fiveminutes.

In carrying out the invention a plurality of tubs 5 are provided equalin number to the total number of five mlnute intervals occupied duringthe dyeing process. These tubs are supported in a. row by a suitableframework 6 and are arranged in juxtaposition to each other so as tooccu y a minimum space. Secured to opposite si es of the tubs andframework and extending thereabove are a plurality of frames 7 arrangedin pairs and each frame having a cross piece 8 arranged in an inclinedposition and combining with the cross piece of the associated frameto.form an inclined platform for a purpose which will presently appear.The pair of frames at the extreme left of Figure 1, which is the inletend of the machine, are attached partly to the framework 6 oft-hemachine, and partly to the first tub 5, the right-hand extremities ofsaid frames being secured to said tub at approximately the middlethereof. The next pair of frames in the order of succession are securedto the first-named tub and also to the succeeding tub with the longervertical members of said frames arranged adjacent the shorter members ofthe preceding frames and forming a space therebetween for a purpose tolater appear. The succeeding frames 7 are arranged in a like manner andby this arrangement it will be apparent that the platform formed by eachpair of frames will overhang two adjacent tubs with the space betweenadjacent pairs of frames disposed substantially at the middle of eachtub. The pair of frames associated with the last tub at the delivery endof the machine is provided with an extension 9 secured to the framework6 and forming a horizontal platform upon which the various fabric-carrying drums 11 are finally deposited after a drum 11 into a tub and liftthe same therefrom at the termination of a definite period of time. Theupper ends of the various rack bars are connected by a drum supportingmember or bar 10. At the beginlng of the operation of the machine thesupporting member 10 and the various rack bars 13 are elevatedsufficiently to permit a drum 11 to be rolled downwardly on the firstplatform until the trunnions 1 f of drum 11 are resting upon thesupporting bar 10. Then, as the bars 10 and 13 are lowered the drummoves along the bar 10. by reason of the inclination of the platform.until the trunnions engage in the space between the shorter end of thefirst platform and longer end of the next succeeding platform. Con--tinned downward movement of the bars 10 and 13 will then lower the drum11 into the tub until said trunnions engage the bearings 15 secured tothe top of the tub. In this position a portion of the drum containingthe fabric which is wound thereon in any suitable manner will beimmersed in the solution in the tub 5. Each trunnion 14 may be rovidedwith inner and outer collars 16 which will be effective to preventshifting of the drum in a direction along its axis while in operation.

The mechanism for operating the bars 10 and 13 at predeterminedintervals preferably comprises a horizontally arranged shaft 17 mountedin bearings 18 adjacent the tops and on both sides of the tubs 5. At theinlet end of the machine each shaft 17 carries a worm gear 19 whichmeshes with a similar gear 20 carried by the adjacent end of 'atransversely extending shaft 21 supported in the framework 6. At one endof the shaft 21 the same is provided with a pulley or other drive 22which is connected by a beltto move the rack bars 13 upwardly and withthe bar 10 engaging the undersides of the trunnions 14 the varlous drumswill be lifted from the tubs, and when said motor is reversed the rackbars and consequently the drums supported thereby will be lowered intothe tubs. .When each drum reaches the extremity of its upward movement,the trunnions thereof engage pivoted arms 24: which, in normal position,form extensions of the upper ends of the platform 8. The trunnions liftthe arms which then restore to normal, whereupon they form supports forthe drum until the same has rolled downwardly onto the platform proper.

lVhile the drums are immersed in the tubs and the trunnions thereof areresting upon their bearings 15, the invention provides means forcontinuously rotating said drums in order that the fabric on the drumswill become thoroughly saturated in the solutions in the various tubs.To this end there is provided a shaft 25 on each side of the tubsmounted in suitable bearings 26 and arranged in parallelism with theshaft 17. The forward end of each shaft has a worm gear 27 meshing witha similar gear 28 carried by the adjacent end of a transversely disposedshaft supported by the framework 6. One end of the shaft 29 carries apulley 30 supporting a drive belt 31, which is connected to a suitablesource of power, such as a motor (not shown). On each shaft 25 there isa plurality of worm gears 32 each of which is designed to mesh with asimilar gear carried by one of the trunnions 14 of each drum when thetrunnions of said drum are resting in their bearings 15; The shaft 25 iscontinuously driven so that during the intervals of time that the gears32 and 33 are meshing the drums will be revolved. \Vhen the rack bars 13are operated to lift the drums from the tubs the initial upward movementof said drums will disengage the gears 33 from the gears 32 and thuscause a cessation of the rotation of said drums.

Above each of the tubs 5 in which the fabric is cleansed by witer thereis mounted in any suitable manner a shelf 34 (Figure 1) which supportsan apertured water pipe 35 connected to a suitable source of supply. Thewater from said pipe flows off of the shelf 34 in the form of a sprayand onto the fabric so that the latter becomes saturated and cleansed.As the water drips from the fabric it falls to the bottom of the tub andflows therefrom through a drain 36 depending from said tub.

Briefly, the operation ofv the machine is as follows:

With the supporting members 10 and rack bars 13 partially elevated adrum containing a fabric is placed uponthe platform of the frames 7 atthe inlet end of the machine and said drum is allowed to roll along saidplatform until its trunnions come in contact with the supporting member.Then as the rack bars.13 are lowered the drum consequently movesdownwardly along the platform and finally into the first tub-5. When thegear 33 of the drum engages the ear 32 carried by the shaft 25 rotationof the drum will commence and continue until a predetermined period oftime has elapsed at which time the shaft 17 the rotation of which isstopped by the stopping" of themotor driving the same when the rack barshave reached the extremities of their downward movement, will again berotated but in an opposite direction so as to start the upward movementof the rack bars. This'upward movement disconnects the drum from theshaft 25 stopping the rotation of the former and the movement continuesuntil the supporting member 10 reaches the extremities of its upwardmovement, at which time the drum trunnions will engage over the arms 24and be deposited upon the platform of the second set of frames 7. Theoperator observing the movement of the rack bars will deposit a seconddrum upon the first platform about the time that the forward extremityof the bar 10 intersects the plane of the platform so that said seconddrum will roll down the platform and onto the bar 10. This operation isrepeated at the termination of each definite period of time and uponeach operation' of the rack bars each of the drums is lowered into atub, elevated therefrom and advanced to the next succeeding tub untileach drum has passed through all of the various solutions and beendeposited upon the platform 9 at the delivery end of the machine.
